kotlin-android-starter

kotlin-android-starter copied to clipboard

i dded another project as module and tried to add this starter in gradle using this line :

implementation project(path: ':library')

and when i'm trying to sync i'm getting the following error :

Unable to resolve dependency for ':sample@debug/compileClasspath': Could not resolve project :library.

Could not resolve project :library. Required by: project :sample

i researched it on stack overflow, and the only thing that almost worked for me is to rename my gradle line to this :

implementation project(path: ':library', configuration: 'default')

my sync did work, but i couldn't import any of the project files.

i know that the issue is that the configurations is not identical , but i don't know what i should do to fix this.

This is the problem

• Required com.android.build.gradle.internal.dependency.AndroidTypeAttr 'Aar' and found incompatible value 'Apk'.

I had the same trouble. It's because you want to reach values from an App module. You have to convert it to "Android library" type. Try this https://developer.android.com/studio/projects/android-library.html#Convert I didn't find a way to resolve resources from an app module in another module. The safest way is to organize your project as in this example https://stackoverflow.com/a/34808917
